“Bring Your Own Device (BYOD)” in the enterprise is sweeping the nation.

The number of enterprises supporting tablets and smart phones grew from 60% to 72% in 2011, according to a survey by Good Technology, a vendor of enterprise mobile management systems. The findings are from a recent update to a survey Good conducted in January. A mere 9% said they had no plans to support BYOD.

It should be noted that there is a built-in bias to this survey given that Good customers already have a mobile management system of one type or another and are somewhat predisposed toward smart phones and tablets. The  survey itself does not disclose the number of respondents, but according to a Network World story, it was about 100 Good customers who answered 20-questions posed online. 

The results are interesting, especially if you are in an industry where personal smart phones and tablets are becoming the norm. Financial and healthcare industries are leading the BYOD way while wholesale/retail industries and government are the laggards (see the graphic).

Here are the key findings verbatim from the survey: 

— Highly Regulated Industries Embrace BYOD: Large companies from the Finance/Insurance and Healthcare industries dominate theoverall BYOD picture, with Retail/Wholesale and Government less likely to support BYOD, at least right now.

— Big Companies Get BYOD: 80 percent of those supporting BYOD have over 2,000 employees; 60 percent have over 5,000 employees;and 35 percent have over 10,000 employees.

— Employees Are Willing to Pay for Personal Choice: 50 percent of companies with BYOD models are requiring employees to cover allcosts – and they are happy to do so; 45 percent provide their employees with a stipend or “expense back” option to help subsidize thecost of their mobile device or service plan.

— Offering BYOD Stipend Increases Adoption: Companies that offer BYOD stipends have the highest rate of employees using mobiledevices when compared to companies that require employees cover all BYOD costs themselves, or allow for expense‐back of serviceplan costs, but limit to users with management pre‐approval.

–BYOD Goes Global: Many believe that BYOD “doesn’t work” outside U.S. due to international privacy laws and/or greater exposure tohighly variable roaming costs. Our data clearly shows otherwise – with nearly half (44.9 percent) of respondents indicating they arealready deploying BYOD programs in multiple countries.

What’s the role of the CIO in managing, controlling or limiting BYOD? I found a great story on how companies are managing tablets by the same Network World author who wrote up the survey (John Cox) and I have to share a quote from an IT director at a pharmaceutical company:

“I cringed at the thought of purchasing for our sales force 100 devices running iTunes. I was used to a certain amount of control [over client devices]. This was outside my comfort zone.”

Have you found your BYOD comfort zone?
